The Wind satellite was deployed to study radio waves and plasma that occur in the solar wind and in the Earth's magnetosphere. The spacecraft's original mission was to orbit the Sun at the L1 Lagrangian point, but this was delayed to study the magnetosphere and near lunar environment when the SOHO and ACE spacecraft were sent to the same location. Wind has been at L1 continuously since May 2004, and is still operating as of May 2019. Wind currently has enough fuel to last over 50 years at L1. Wind continues to collect data and as of May 10, 2019 has contributed data to over 5000 refereed scientific publications.
